<div>Dear Wien2k users,<br>
</div>
I want to calculate the energy of atoms using Wien2k_17.1. We place an atom e.g. C in the box size of 25 Bohr and follow all the default convergence criteria for the calculation. We are trying to calculate both spin-polarized and unpolarized cases taking only
one kpoint (1 1 1). In the spin-polarised calculation, we are facing the energy convergence problem i.e. ETEST is fluctuating even after 40 cycles. And in the spin-unpolarized case, we are facing QTL-B Error after some cycles. We would like to request to give
some suggestion to solve the above problem. Thank you in advance.<br>
